[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5The present invention provides a technical solution: a sizing mechanism for an aluminum rod hot shear furnace, comprising: a frame body 1, a moving assembly 2, and a connecting assembly 3. The frame body 1 is installed on the aluminum rod hot shear furnace, a connecting arm 4 is provided below the frame body 1, and a trigger mechanism 5 is installed in the connecting arm 4; the trigger mechanism 5 is a prior art and will not be described in detail here. The connecting assembly 3 is provided at the bottom end of the frame body 1, and the connecting assembly 3 includes a first connecting block 31 provided at the top of the connecting arm 4, a second connecting block 34 provided on the connecting arm 4, and a bolt body 32 for fixing the first connecting block 31, the second connecting block 34 and the connecting arm 4; the moving assembly 2 is provided between the frame body 1 and the connecting assembly 3, and the moving assembly 2 is used to move the connecting assembly 3. The moving assembly 2 includes a screw body 22 that rotates laterally at the bottom end of the frame body 1, a transverse guide rod 23 that is welded and fixedly installed in the frame body 1 below the screw body 22, and a servo motor 21 that is installed on one side of the frame body 1 through bolts and nuts to drive the screw body 22 to rotate. The connecting assembly 3 also includes an arcuate thread groove 35 opened on the side close to the first connecting block 31 and the second connecting block 34 and cooperating with the screw body 22, and a reserved hole 33 in the first connecting block 31 and the second connecting block 34 below the arcuate thread groove 35 for the transverse guide rod 23 to slide.

[0024] The first connecting block 31 and the second connecting block 34 are assembled correspondingly, so after long-term use, when the arc-shaped thread groove 35 is worn, it can be disassembled and replaced, so it can be used for a long time, avoiding the need for a large number of images after wear; since the first connecting block 31 and the second connecting block 34 are threadedly connected to the screw rod body 22 through the arc-shaped thread groove 35, the first connecting block 31 and the second connecting block 34 are slidingly connected to the transverse guide rod 23 through the reserved hole 33, and the transverse guide rod 23 guides the first connecting block 31 and the second connecting block 34. Therefore, after the servo motor 21 is turned on, the output shaft of the servo motor 21 drives the connecting assembly 3 to move during the forward and reverse rotation process, and then drives the connecting arm 4 to move, which is conducive to the trigger mechanism 5 to measure the aluminum rod.

[0025] A sizing mechanism for an aluminum bar hot shear furnace also includes an assembly component 6, which is arranged on the connecting component 3 and is used to assemble and fix the second connecting block 34 and the first connecting block 31. The assembly component 6 includes a vertical through hole 61 opened on the first connecting block 31 and a cylindrical plug 62 inserted into the first connecting block 31, and a vertical through hole 61 for inserting the cylindrical plug 62 is opened on the second connecting block 34. The assembly component 6 also includes a horizontal plate 64 fixed to the same side of the two cylindrical plugs 62, and a spring 63 welded between the horizontal plate 64 and the first connecting block 31, and the spring 63 is located outside the cylindrical plug 62. The horizontal plate 64 and the cylindrical plug 62 are fixedly connected in an integrated manner, and the integrated horizontal plate 64 and the cylindrical plug 62 form a reset structure through the spring 63.

[0026] Pull the horizontal plate 64 upward, the cylindrical pin 62 moves upward, and the spring 63 is stretched to increase the length. When the second connecting block 34 and the first connecting block 31 are aligned, the horizontal plate 64 is released. At this time, under the action of the spring 63, the cylindrical pin 62 moves downward and is inserted into the vertical through hole 61 to fix the first connecting block 31 and the second connecting block 34. Working principle: During assembly, the first connecting block 31 and the second connecting block 34 are assembled on the outer walls of the screw body 22 and the transverse guide rod 23. At this time, the first connecting block 31 and the second connecting block 34 correspond closely. The transverse plate 64 is loosened, and the cylindrical pin 62 is reset and moves downward under the action of the spring 63. The cylindrical pin 62 is inserted into the vertical through hole 61 on the second connecting block 34, firmly fixing the first connecting block 31 and the second connecting block 34. Subsequently, the servo motor 21 is started, and the output shaft of the servo motor 21 drives the screw body 22 to rotate. With the cooperation of the transverse guide rod 23 and the reserved hole 33, the connecting arm 4 moves smoothly, and at this time drives the trigger mechanism 5 to move. The aluminum rod can be measured and processed by utilizing the action of the trigger mechanism 5.
